iSCSI
Each controller has a unique, permanent hardware address. Each controller host port
has a unique, user-defined IP address.
The following table shows example hardware addresses and port IP addresses.

Both controllers have the same unique, permanent node WWN. Each controller host
port has a unique port WWN that is based on the node WWN. The WWN format is:
